A hardware retailer near me has a sweet deal on a same model GPU that I currently have, which got me thinking about getting an SLI setup to bump my FPS up a bit and generally stabilize the performance more.

Given that MWO is the game that I spend most time with, my main concern is how does this game handle SLI? Any experiences?

From what I've heared it's bad with this game.

SLI would sometimes (rarely) work perfectly for me, but most of the time it was awful. Going from SLI GTX 660 TIs to a single GTX 980 was a major difference in visual quality, stability, and playability.

Running 2X980s on an older 2500k at 4.6ghx I get 60-80 FPS on most newer maps. On the older maps (Canyon Network and Frozen City) I get around 100-110. On most CW maps it hovers between 70-80. Settings are mostly Ultra, no AA, Afterglow off, PP medium, Shadows high. Res is 1440.

Single 980 I never saw it pass 90 FPS, most of the time I was seeing 60-70 FPS with occasional dips into the 40-50 range. (All of this was Pre-redesign on River City/Forest Colony.)

But with SLI, it is only worth it if you are already running a top end card. If you have something lower end like a 970 or 960 spend your money on a 980ti. Always go with the highest card you can afford before you add a second card.

One thing I forgot to mention, is that this game is horribly optimized and the maps have a lot of excessive and poorly used particle and texture effects that will bog down cards with lower memory counts, like the 950 and 960.

If you're going to SLi, make sure you use Nvidia Inspector to modify the MWO profile. This is the SLi compatibility bits that I used to get SLi working on my dual GTX 765m Laptop:

Also, I force AFR for one of the settings further down as well (not on the laptop atm, so can't take another screenshot)

Well it seems to be luck of the draw then, I've been gettinng similar performance as healybob but with all max settings/MSAA @ 5770x1080. I've never played with the Nvidia profiles as I wouldn't know what I was doing.

As for the badly optimized game, this has been majorly improved somewhere in the last 4 months. Before this optimisation I was lucky to reach 60FPS.

All this on a i7-3770 and two GTX 780's.

Dual 970's here

When I finally got got it running I was actually disappointed I didn't see all that much of an improvement over my single card performance, it wasn't the boost I was hoping for.

That being said, in my experience it's not any worse than a single card, it definitely keeps.

tl;dr SLI works fine, but not as much as it does for other games.

This game is about 75% CPU driven, try getting in a drop and pushing Rshift + F11. If your FPS increased significantly then your GPU is already being held back and the biggest gain you'll get is from a CPU with high clocked cores not lots of low clocked cores.
